The Wacker Neuson GFCI Module is a genuine OEM component designed for the GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, GPS6600A, GPS9700, GV3800, GV5600, and GV6600 series portable generators. As a direct OEM replacement sourced from Wacker Neuson, part matches the original specification for a drop-in installation with no adaptation needed. This module covers an exceptionally wide range of GP and GPS generator configurations, including standard, wheel kit, electric start, CARB, EPA, and CSA variants. Keeping a verified replacement on hand means your generator stays operational and protected whenever the original unit reaches end of life.
Key Features
- Correct Trip Sensitivity: — Genuine OEM construction ensures the GFCI module trips at the precise leakage current threshold required by the original circuit design, maintaining the protection level Wacker Neuson engineered into these generators.
- Direct Plug-In Replacement: — Matches the original connector, mounting footprint, and wiring harness interface of the GP and GPS generator outlet panel for a straightforward swap.
- Broad Generator Compatibility: — Fits GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, GPS6600A, GPS9700, GV3800, GV5600, and GV6600 series across EPA, CARB, and CSA configurations.
- Restore Full Outlet Function: — A failed or nuisance-tripping GFCI module renders protected outlets unusable; this replacement restores all downstream receptacles to full rated capacity.
- Electrical Safety Compliance: — GFCI protection on portable generators is required for compliance with OSHA and NFPA 70E ground-fault requirements on construction sites; using a genuine OEM module preserves that compliance status.
A GFCI (Ground Fault Circuit Interrupter) module monitors the current flowing out of a circuit and the current returning to it. If those two values differ by even a small amount — indicating current is leaking through an unintended path such as a person or a wet surface — the module cuts power to the outlet within milliseconds. On portable generators used on construction sites, this protection is a critical safety layer for operators and connected equipment. When the GFCI module fails, it may refuse to reset, trip immediately under load, or stop providing fault protection entirely, any of which leaves workers exposed or the generator unable to power tools through its protected receptacles.
